REGULATOR FR HOT-WATER' HEATING SYSTEMS.

Application led December 13, 1913.

This invention relates to an automatic regu# lator for hot water heating systems, and the inventionconsists in the construction and combination of parts substantially as hereinafter shown and described and more particularly pointed out in the claims.

In the accompanying 'drawings the single figure shows a sectional elevation ofthe regulator. l

The regulating device indicated as awhole by B is `provided with such means internally that vthe pressure ofthe water within the systeml in which the regulator is installed will be automatically.regulatedwithin certain lng respectively in casings 10 and 13 which are integral portions of the main body B; The plunger and 20 disposed relatively above and below the main water inlet or entrance 7 and both valves open downward under the action Vof plunger 10 and the spring 9 which bears on said plunger from above. is shown as confined in a tension 29 threaded uponl of bodyV above the plunger casing or portion10. Y e.

The plunger 13 has a valvei15 rigid therewith and adapted to seat downward upon seat 21 in the casing 21. The toprwall of body B connects the two casings or portions 10` and 21 therein and is provided with a duct 27 leading from one casing to the other for a purpose hereinafter described. A spiral spring 14 is seated on valve 15 in the casing and the extension 28 above the same, as shown, and which extension or cap corresponds to capf29 and serves as a housingv for said spring and normally holds the valve 15 and its plunger 13 on their respective seats, the said plunger being seated at 23 within the casing 13. A small orifice 24 enters said casing from the otherwise open water space within the body B below plunger 13 and serves to take care of excess pres- Specication of Letters Patent.

The water passes to the heater, not shown, through the bottom opening or outlet 11 in into said body from beneath andis provided with a comparatively fine wi objectionable particles into the regulating device when expansion of water occurs and backs into the same. opening in the bottom of body B occupied by pipe connection 12 is large enough to permit the plunger 10 and its valves to be removed and replaced through the same.

The opposed end surfaces of the. two valves 17 the opposed surfaces of the valve 17 and the plunger 10V also have the same area, so that the pressure on bothv valves, and the pressure within the receptacle is also equal on the plunger and the upper end of valve 17. The opposedend surfaces of plunger 13 and valve 15 are also of equal area to counterbpalance the pressure from within the regulator. Thesaid plungers and springs, furthermore, are so .ar-l

ranged and proportioned that the pressure of the water entering through inlet 7 Vis automatically regulated within certain `predetermined limits, and the water pressure upon the lower enlarged end of valve 19 is counterbalanced by the pressure of spring 9. It

follows that when the water pressure inthe system through opening 11 is less than the plunger 16 ,and

pressure of said spring the its attached valves will be depressed from `said body as hereinafter fully 1 the reducer connection 12 which is screwed re mesh Y screen 30 adapted to prevent the passage of The'enlarged threaded and 19 are of the same area, and

bottom of the plunger is also exposed to the water pressure within the regulator. Plunger 13 is counterbalanced by spring 14, but when the water in the boiler is heated and begins to expand the water Within the regulator will pass through the orifice or duct 24 to overcome the pressure of spring 14 and poundsto be* set to permit valve 15 to open when. a'

After suflicient relief the said valve `and plunger 13 and 15 will again return to normal underfpressure ofspring. 14 and the lirst con.- dition be restored. The action is automatic and repeated indefinitely as the conditions arise. Obviously the motion of plunger 13 cannot be rapidas the orifice 24 is compara tively small, and otherwise the chamberor space in` casing 13 beneath 'said plunger is closed; Itfwill alsobe noticedthat' the eX- haustpassageBf is of suchsize at itsmouth as'to extend above val've 15,-so` thatV any slrghftv leak past the valve will drain into the sewer-and:thetransverse duct 27 inthe top` 'wallofthe body Bf'rom above plunger 10 "serves'to' drain therefromintothe sewer in" like'frnannerlv "Set screws 36 over the springsgjand 14-respectivelyserve to fix the tension oft' the springs watery pressure may be` maintained in the systemr eitherhigherior lower than-the pressureinthewater' supply through inlet 7.
